These guys give awesome customer support and they know their stuff.
We had quite a high level of scorpions and I had been spraying around the house with limited success. With a new grandchild now arrived who regularly comes over, I was "directed" to come up with a solution. Coincidentally I was given this company as a reference by a co-worker who has a rental in Chandler (with a large number of scorpions) and the renters had been freaking out, also my next door neighbors had two young kids and had gone to this company to resolve their issues. Both are very happy with this company
Anyways they have a very sophisticated package / program which takes several months to implement. This involves a mix of education, inside sealing, external sealing, and chemical spraying etc. etc. They also have a calendar which tells you when to spray etc. . Did you know that scorpion levels are highly correlated to moon phases?
Anyways - the program costs a bit of money, but in this case you certainly get what you pay for and as I said the service is outstanding. An example is they sealed the trap doors during the internal house seal (which took ~ 6 hours for my house), but they were very happy to come back around and do some re-sealing after we had some other workers do work on our roof space.
As Georgia will tell you it's not an over night fix to get rid of the scorpions - the program can take several weeks or months depending upon what time of the year it is. Having said that since these guys did their work we have only seen one scorpion in the last 4 - 6 months and I must admit the program created a little complacency on my part since there have been so few scorpions around I am not spraying as frequently as I am supposed to.
These guys seem to be pretty busy - so it may take a week or so to schedule you in. However getting rid of scorpions is not something you can do in a week - it's a many months long program; so if your going to do it correctly - go with this company. HIGHLY RECOMMENDED
